Given numbers are 102, 153, 484, 643

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 153 are 3 x 3 x 17

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 643 are 643

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 102, 153, 484, 643

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(102, 153) = 306

GCD(102, 153) = ( 102 x 153 ) / 306

= 102 / 153

= 102

Step2:

LCM(51, 484) = 24684

GCD(51, 484) = ( 51 x 484 ) / 24684

= 51 / 484

= 51

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 102, 153, 484, 643 is 1
